Let's look at these rare succulent Plants. Drought-tolerant trees have long roots that go deep underground. Too much moisture will be retained in soils that are rich in clay, peat, moss, and coconut coir. If you gave them the nutrients toward the end, they wouldn't have much time to absorb them before entering a period of slowed growth and dormancy. They don't require as much sunlight than other succulents. They can also thrive indoors. This succulent doesn't complain of poor soil conditions as long as the drainage is good and it loves full or partial sunlight.
